  The invention relates to a method for improving the drainability of mechanical pulp or pulp mainly con­taining mechanical pulp by means of enzyme treatment by adding to the pulp at least one hemicellulose-dis­solving enzyme or an enzyme preparation containing at least one hemicellulose-dissolving enzyme and being substantially free from cellulose-dissolving enzymes. The enzyme treatment according to the invention not only improve the drainability of the pulp but also retains the strength properties of the pulp since no cellulose-dissolving enzymes are used.

  本发明涉及一种通过酶处理改善机械纸浆或主要含机械纸浆的纸浆排水性的方法，方法是在纸浆中加入至少一种半纤维素分解酶或含有至少一种半纤维素分解酶且基本不含纤维素分解酶的酶制剂。根据本发明进行的酶处理不仅能改善纸浆的排水性，还能保持纸浆的强度特性，因为没有使用纤维素分解酶。

  A medium susceptible to spoilage enzymes contains a halogen compound selected from alkali metal tetrahaloaurate, a heterocyclic compound containing at least two ring nitrogen atoms and at least one nitrogen-halogen bond, an iodonium compound and a sulphonamide containing at least one nitrogen-halogen bond. The medium may be a an aqueous solution containing soluble cellulose in which the spoilage enzyme is cellulase, for example as in an aqueous paint. the presence of the halogen compound reduces the extent of thinning of the solution. Deterioration due to lipases, proteases or amylase can also be reduced.

  The present invention relates to novel xylanases purified from the microorganism, Microtetraspora flexuosa. Each biochemically unique xylanase is thermostable and has optimal activity in alkaline conditions. The present invention is also directed to methods that utilize either the whole enzyme system or one or more of the above purified thermostable xylanases obtained from Microtetraspora flexuosa. These enzymes are excellent candidates for enhancing the delignification and bleaching of pulp. Furthermore, treating the pulp with the above enzymes prior to bleaching may reduce the amount of chlorine containing and/or peroxide chemicals required in the bleaching process.

  本发明涉及从微生物曲霉微孢子菌（Microtetraspora flexuosa）中纯化的新型木聚糖酶。每种生物化学上独特的木聚糖酶都具有恒温性，并在碱性条件下具有最佳活性。本发明还涉及利用整个酶系统或一种或多种上述从柔毛小四孢属微生物中纯化的可恒温的木聚糖酶的方法。这些酶是提高纸浆脱木素和漂白效果的极佳候选酶。此外，在漂白前用上述酶处理纸浆可减少漂白过程中所需的含氯和/或过氧化化学品的用量。
